I see windshield being toughest. Seats being a second but you do have flexibility for minimal interior as a possibility, without being fugly. Abandon the linc crap and go analog, a 343excal can be had with pcm 80 (good used) for less than $5k. Convert to ZO (guessing $3.5k). That’s $8500. Add 5k to piece part of a clean interior together, $12.5. Add $5k for incidentals which is realistic IMO, $17.5, if the boat and trailer were together for $5k that’s $22.5k. Go with that dirty word, PerfectPass, and save $2500 and have a good pull.
Now, if you were to think about putting a price to your time, even subrate it at $25 an hour, FUGETABOTIT go buy a whole boat. If you like to tinker, it’s fun project in my eyes.
I once built an NWZ, no more than 3 items were from the same boat, in the water in less than 2 days. I started with Clean enough hull, new carpet installed, then the race was on with assembly of everything else. Granted I spent over 2 years sourcing parts and storing parts, I do not recall any major fabrication bc all parts were from NWZ’s or 2001’s. I did have help installing and aligning and tuning motor. That was gauges installed, wiring harness in, plumbed, used complete motor and tranny, I put complete correct interior in. Within 48 hours it was running 47 mph and only problem for a year was in gas gauge. Then I sold it to family for $5k! That was pre wife and kids.
